A super fishing explosive can be made by mixing Guam and Rubium in a vial of water, giving 55 Herblore experience. It requires level 31 Herblore and the completion of Kennith's Concerns.
The difference between this explosive and the Fishing Explosives sold from various Slayer Masters, is that they cause 150 damage to the Mogre as it becomes lured.
